Abstract
La présente invention se rapporte à un dispositif lumineux de véhicule (1) comprenant : - un élément optique (10) présentant une surface génératrice (12) de caustique contrôlée de manière à propager un motif, - une partie de montage (2) sur laquelle est destiné à être monté un générateur de faisceau (3) de rayons incidents sur ladite surface génératrice, l'élément optique étant agencé de manière à ce que ce motif soit propagé sur un intervalle utile et selon une répartition photométrique donnée, de manière à former une partie d'un faisceau lumineux d'éclairage, cette partie présentant une coupure.The present invention relates to a vehicle lighting device (1) comprising: - an optical element (10) having a caustic generating surface (12) controlled so as to propagate a pattern, - a mounting part (2) on which is intended to be mounted a beam generator (3) of rays incident on said generating surface, the optical element being arranged so that this pattern is propagated over a useful interval and according to a given photometric distribution, so as to form part of an illuminating light beam, this part having a cutoff.
